The HDCV is a double pilot operated, hydraulic check valve for use in blocking or load holding circuits
The valve allows flow from "v" ports to "c" ports, while normally blocking flow in the opposite direction. Flow will be allowed from "c" to "v" when pressure is applied to the opposite side "v" port. The valve has 2.3:1 pilot ratio, so at least 43% of the load pressure held at either "c" port is required at the opposite "v" port to open the flow passage
